Convert Kilograms to Carats
1 kilogram is 5,000 ct. One kilogram is exactly 5000 carats.
One kilogram is 5000 carats. To convert kilograms to carats, multiply by 5000; to go the other way, divide by 5000 or multiply by 2.0000 × 10^-4. The factor is exact rather than rounded: it follows from NIST Handbook 44. The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.

How do you convert kilograms to carats? The converter and the working
- 1.Take the measurement in kilograms.
- 2.Multiply by 5000 — that is how many carats fit in one kilogram.
- 3.To go back the other way, divide by 5000, or multiply by 2.0000 × 10^-4.
Worked example: 25 kilograms to carats
- Formula
- kg × 5000 = ct
- Arithmetic
- 25 × 5000 = 125,000 ct
- Answer
- 25 kg = 125,000 ct
The factor is exact, so this figure is exact too — only the display is rounded.

What is a kilogram?
The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.
What is a carat?
Exactly 200 milligrams, fixed by international agreement in 1907 after centuries of local carats. It weighs a gemstone; the karat that grades gold is a different word for a different thing — purity in twenty-fourths.
How many carats are in a kilogram?
One kilogram is 5000 carats, exactly. Going the other way, one carat is 2.0000 × 10^-4 kilograms. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
